Initial Research Question

  • Each of the thirty Major League Baseball (MLB) teams plays in one of thirty stadiums or baseball parks.

  • Of the thirty MLB baseball stadiums, 22 of them are open-air.

  • We would like to know if changing climate and weather patterns might have an effect on either team performance or game attendance.
